Akuvox S535 On-Wall Mounting Box for Expansion Unit

The S535 can take an expansion unit under its main panel: a fingerprint reader, an induction loop for hearing aids, or LTE. With the unit attached the door phone grows from 210 mm to 260 mm tall, so it no longer fits the standard S535 boxes. Akuvox makes a separate set for that longer version, and this is its on-wall box.

On-wall means the box is screwed to the face of the wall and the S535 with its module is fixed onto it, with no recess to cut. That suits a finished wall, a cladded gate pillar or a rented building where breaking into the masonry is not an option. Where the wall can be opened, Akuvox's in-wall box for the S535 with modules gives a flush finish instead.

Order it together with the S535 and the expansion unit you plan to use. The standard S535 boxes are sized for the base unit alone and will not take the extra length.
